【摘要】：在f/2全營養(yǎng)培養(yǎng)條件下,采用共培養(yǎng)以及濾液交叉培養(yǎng)的方法研究了中肋骨條藻(Skeletonema costatum)和微小亞歷山大藻(Alexandrium minutum)之間的競爭作用,結(jié)果表明:微小亞歷山大藻指數(shù)生長后期的無藻細胞濾液對中肋骨條藻的生長沒有抑制作用,但中肋骨條藻濾液明顯抑制了微小亞歷山大藻的生長,且抑制作用隨著中肋骨條藻濾液比例的增大而增大,他感作用是影響這兩種微藻間競爭的重要方式之一;通過向培養(yǎng)基中添加自他感物質(zhì)標(biāo)準(zhǔn)品15S-hydroxy-5Z,8Z,11Z,13E,17Z-eicosapentaenoic acid(15(S)-HEPE)考察其對中肋骨條藻自身以及微小亞歷山大藻生長的影響,發(fā)現(xiàn)15(S)-HEPE在中肋骨條藻濾液中并不是能夠抑制微小亞歷山大藻生長的他感物質(zhì),今后應(yīng)進一步深入分析中肋骨條藻釋放的抑制微小亞歷山大藻生長的他感物質(zhì)。
[Abstract]:The competition between Skeletonema costatum and Alexandrium minutumin was studied by co culture and filtrate cross culture under the condition of f / 2 total nutrition. The results showed that the non-algal cell filtrate in the late stage of the growth of Alexandrium minimus had no inhibitory effect on the growth of S.costatum, but the filtrate significantly inhibited the growth of Alexandrium minima. The inhibitory effect increased with the increase of the ratio of the filtrate, and the allelopathy was one of the important ways to affect the competition between the two microalgae. The effects of 15S-hydroxy-5Z ~ (8) Z _ (11Z) ~ (13) E ~ (17) Z-eicosapentaenoic acidoic acido _ (15) on the growth of S.costatum and Alexandrium minimus were investigated by adding 15S-hydroxy-5Z _ (8Z), a standard material of allosensory substances, to the culture medium. It was found that 15 ~ (15) Schi-HEPE was not an allelopathic substance that could inhibit the growth of Alexandrium minimus in the filtrate of P.costatum. In the future, it is necessary to further analyze the heterosensory substances released by S. costatum to inhibit the growth of Alexandrium minima.
